Peavey DPM3SE advice needed

Hi, I have a currently non working Peavey DPM3SE. It has some corrosion on the main board and a crack across the lower part of the display board which has a working repair of sorts. Everything else is fine. Would i be best to attempt a repair or would it be worth more to sell the full thing as a donor unit? I am based in the UK.

I can take pics if required…

Many thanks
